Walnut and Dried Cherry Bars Recipe : Ellie Krieger : Food Network
I understand your plight, especially about avoiding high fructose corn syrup. I've been known to indulge in Nature Valley or Fiber One bars because they are quick, easy, and keep me full for a long time when I'm in a hurry. Never thought of making them myself but it's something to look into.
After experimenting with various breakfasts since my weight loss quest began (lost 40lbs already) I found that the breakfast that keeps me feel full and fueled is low fat greek yogurt with a number of toppings, much like the ones you want to include in your breakfast bars: honey, walnuts, blueberries/fruit, sunflower seeds, flaxseed, almonds, etc. Your body is probably used to the dairy from oatmeal anyway if that's how you make it and yogurt is a great source of protein.
In looking around I didn't see many recipes for breakfast bars that didn't include some kind of oil. I fail to see how oil can be compromising to your health, unless this has something to do with being a "fanatic."
